How is Geothermal Heating Different than a Boiler or Furnace?

Monday, October 8th, 2012

If you need a new heating system in Quakertown, there are quite a few options to choose from. But before we can talk about the differences between boilers, furnaces and geothermal systems we need to understand how they work.

How a Boiler Works

Boilers, like most traditional heating systems, require a fuel source, normally oil or gas, which is combusted in exchange for heat. In the case of a boiler, that heat is transferred to water that is circulated to radiators in each room where the heat from the water is expelled into the air.

How Furnaces Work

With furnaces, the heat generated by the burning of fuel is transferred to a piece of metal called a heat exchanger. The furnace blows cool air from the house over the heat exchanger which warms the air and it is then delivered to the rest of the house using a series of ducts.

How Geothermal Systems Work

A geothermal system uses a pump to circulate liquid, sometimes water or a mixture of anti-freeze and water, into the ground where it is either heated or cooled—depending upon the needs of the people in the house.

The Differences between Boilers, Furnaces and Geothermal Systems

The main difference between a geothermal system and a boiler or a furnace is that it doesn’t require any kind of fuel source. The energy for the geothermal system is actually in the ground. If you dig about 10 feet into the ground, the temperature of the soil stays at an almost constant 55° F no matter what the temperature of the air is above it. When the air in the home needs to be cooled, a geothermal system absorbs the heat from the air and transfers it into the ground. When the home needs to be warmed, the process is reversed: heat from the ground is absorbed by the liquid in the pipes and transferred to the air in the home.

The only energy being used is the electricity to run the heat pump that circulates the liquid in the pipes and the air handler to distribute the conditioned air.

Heating Guide: Boiler Maintenance

Monday, September 24th, 2012

If you own a boiler in Jamison, regular maintenance is very important. Performed in the fall, before your boiler is turned on for the first time, this maintenance will ensure your system works properly and efficiently for the coming months. Here are a few of the tasks performed by a Jamison heating professional during a maintenance call visit:

  • Clean Surfaces – The front and rear doors to the boiler are removed and the surfaces are all vacuumed and cleaned carefully.
  • Gasket Repair – All gaskets on the doors are checked and replaced if necessary to ensure your system works properly. Similar repairs are performed on the hand hole and man hole plates and the low and auxiliary low water cut off controls.
  • Burner and Pilot – The burner plates and pilot light are thoroughly inspected and cleaned. A technician will also check the pilot electrode and then test the pilot to ensure it works as intended.
  • Air Damper – The air damper and blower are both cleaned and tested for potential issues before turning back on.
  • Burner Adjustment – The burners are tested and adjusted for proper combustion and tests are performed to ensure the flame is right. Flame safeguard and safety trip checks are also performed to ensure the system will turn off as needed.
  • Control Piping – The control piping plugs are removed and cleaned, as is the entire pathways between

Boiler maintenance is the most effective way to ensure your heating system continues to work properly throughout the coming winter. Because of the nature of a boiler and the fact that most systems use natural gas or oil, it is important that a professional be the one to perform the above tasks.
